y STACKER FOR CONFECTIONS.

Specification of Letters Patent.

Patented Sept. 25, 1917.

Application led March 13,1914.l Serial No. 824,441.

T0 all whom z' may concern: Be it known that we, WILLIAM J. SWARTZ and EDWARD H. WAUGH, citizens of the United States of America, residing at Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Stackers for Confections, of which the following is a specification.

Our invention has for one of its objects to provide a construction of the above type wherein the articles are stacked in a more efficient manner.

A further object resides in a novel provision for supporting one or more stacks of articles.

Other objects will be set forth as our description progresses and those features of construction, arrangements and combinations of parts on which we desire protection, will be succinctly defined in our annexed claims.

Referring to thev accompanying drawings, illustrating a preferred embodiment of our invention, wherein like characters of reference indicate like parts throughout:

Figure 1 is a side elevation of our improved stacker.

Fig. 2 is a top plan View of the stacker' and a fragmentary portion of the advancing mechanism.

i Fig. 3 is a vertical section thereof.

Fig. 4 is a fragmentary horizontal section of the stacker.

Fig. 5 is a detailed perspective of a portion of the swing frame in which the carrier for the article support is slidably mounted. Referring to the drawings by numerals of reference, 1 indicates mechanism for advancing articles to a support 2, which latter i is arranged on a carrier `3, mounted for lmovement at an angle to mechanism 1,

whereby the said support 2 can be lowered as the stacking of the articles thereon progresses. The advancing mechanism 1, as

herein shown, comprises an endless apron which is carried upon -1 rollers 5, fixed to shafts 5', journaled on al stand 6. mechanism may be operated by any suitable intermittent motion device.

Reference numeral 14 indicates a swing frame mounted at the delivery end of advancing mechanism 1, the same comprising side members 14', rigidly connected by an Said yclined position, to thereby insure against accidental dislodgment of the articles stacked.

Support 27 which includes a bottom wall 2", and a top wall 2, is provided with vertical compartments A for reception of the articles in superimposed relation which compartments have open sides (see Fig. 4), facing advancing mechanism, through which the articles are inserted.

Carrier 3 which comprises an open frame is provided on its sides with racks 19 and with outwardly rprojecting guide ribs 18 which latter are slidably received in the guide ways of swing frame 14 and provided with upper and lower stop pins 25, 25 for engagement with lugs 17, 17 respectively, of a rib 17 to thereby limit vertical movement of the carrier.

Racks 19 which are normally in mesh' with pinions 20, are preferably of such length that they will be advanced clear of the said pinions when' the desired number of articles have been received in compartments A. Pinions 20 are fixed to a shaft 21, journaled in stand extensions 7'LL and driven in common with advancing mechanism 1 by a sprocket chain 22 carried upon sprocket wheels 23, 24 of shafts 21 and 5 respectively.

Support 2 is removably engaged in carrier 3, the same seating on thel base 3 thereof against shoulders 30 and having its top wall 2" apertured for reception of a suitvable catch 31, `conveniently comprising a` bolt slidably mounted in carrier 3 and yieldingly pressed into operative position bya spring 32.

Reference numeral 33 indicates a takeoif, overlying the delivery end portion of mechanism 1 and i'ixed, in any suitable manner, to stand extensions 7a. This take-off, whose receiving end portion is preferably tapered and arranged close to or so as to rest on mechanism l is inclined downwardly ving mechanism 1 is stopped. The operator lrier 3 is moved simultaneously with mechanism 1 and each step like movement thereof is of a length lcorresponding or substantially Vcorresponding tothethickness of an article B. Therefore,'the uppermost article stacked will havel itsl upper face substantially flush with the plane of delivery from take-off 33,.

following the adjustment of carrier 3. Vh'en compartments A are filled, advancnow ywithdraws catch 31," thereby freeing support 2 so that it can be tilted outwardly and lifted from the 'carrier 3. When so removedi it will serve asa tray or temporary holder y.for the articles. Another support 2 can now be substituted for the one just removed, following which carrier 3v is elevated and the mechanism againset in operation.

To elevate. carrier 3, swing frame 14 is swung on lts pivots 16 toenable the racks 19 clearing the pinionsiQO. This follows from Y the fact that the pivot' point of swing frame.

1l is' removed from the center of the axis of the wheel which drives the lowering feed of theicarr-ier. Following this the swing frame is freed'so that its weight with thaty of carrier 3 and support' 2 will be imposed through lugs lla on stand extensions 7a at which time racks '19 will be in mesh with pinions 20.

Having thus described our invention,-

what we claim as new, and desire to secure by Letters Patent of the United States of l America, is :-y

1. Inl apparatus ofthe character set forth, article advancing means, a carrier, means for operating. the carrier transversely of the direction of movement of the advancing means, a stack' holding container detachably supported in the carrier and having a lower interlocking engagement therewith, and a. latch for. detachablengaging the u er a :s a n ,portionI of the holdingv meansv to Vsecure the same in the carrier.

f2. In# apparatus of the vcharacter set forth,

article advancing means,l guideways disposed at thewdelivery end thereof and-eX- tending transversely yof the direction of movement ofthe article by the vadvancing Copies of this patent may beobtained for ve cents each, by addressin Washingtonnc.

means, a Vreciprocator'y carrier slidable in the guideways, said carrierV having an open rear and front portion, a stack holding tray securable in theopeningv of said carrier and removable through one side of the carrier, said tray having an open side facing the advancing means, and means for detachably holding the tray in the carrier.

3'. In apparatus of the character set forth, stack forming means supported to have a reciprocatory and a swinging movement, article advancing means for theistack forming means, and operatingimeans for effecting a reciprocatory .movement of the stack forming means, said stack forming'meansv being -held in engagement with the operating mea-ns by gravity and disengaged Vbysaid .swinging movement.

e. Ina vdevice of the` kind set forth,` a carrier having stack forming compartments, a carrier holding frame having seats for receiving said carrier, means for releasably holding the carrier in itsframe, a swingingly mounted guide frame having guiding en.- gagement with thecarrier frame conforming to the vaxes of the stack forming compartv ments, and a carrier frame feeding.y means releasable by the swinging off said guide frame. v

5. In a device of the kind set forth, a` carrier having stack forming compartments, a-

carrierframe adapted to disengageablyfreceive said carrier, a hinged guide` frame, said guide frame and carrier frame having. complemental guides conforming in- .direction with that `of thek stack forming compartthe swinging lof. the guide frame under 'the' action of gravity thereon.

In testimony whereof we affix our signatures in presence ofl two witnesses.- WILLIAM` J.' SWARTZ. EDWARD HJWAUGH. Witnesses: l
